Do you have any face detection examples for desktop?

@RealBBakGosu All the examples are listed at https://mediapipe.readthedocs.io/en/latest/examples.html. We only have face detection example for Android and do not have a version for desktop. However, you should be able to port the face detection tf-lite example to desktop by basing it on the desktop tflite object detection example

• Swap out the desktop object detection pbtxt with the face detection pbtxt
• The face detection Android example uses the mobile camera while the desktop will be loading the input video through a file. As such, you will have to make changes to the first few input calculators to the face detection Android example

Hello if you want to test face detection example on yout desktop, pls download this code and use as a calculator

face_detection_tflite.zip

bazel-bin/mediapipe/examples/desktop/object_detection/object_detection_tflite --calculator_graph_config_file=<face_detection_tflite_path> --input_side_packets=input_video_path=<input_video_path>,output_video_path=<output_video_path>

For example,
bazel-bin/mediapipe/examples/desktop/object_detection/object_detection_tflite --calculator_graph_config_file=mediapipe/graphs/face_detection/face_detection_tflite.pbtxt --input_side_packets=input_video_path=mediapipe/examples/desktop/object_detection/test.mp4,output_video_path=mediapipe/examples/desktop/object_detection/output.mp4

thx to @mgyong

@RealBBakGosu, thanks for composing a face detection graph for desktop use case! Just to clarify, what you have in face_detection_tflite.zip is a graph, and calculators are those nodes in the graph ;)

We definitely will provide more desktop demos in the future releases.
